[0024] The present invention also provides an inductor shielding cover assembly method, using the above-mentioned assembly machine, specifically comprising the following steps:

[0025] S1: The vibration feeding mechanism and the linear feeding mechanism work to send the shielding cover to the linear feeding guide rail;

[0026] S2: The linear feeding guide rail cooperates with the material distribution mechanism to feed the shielding cover into the material troughs one by one. After all the material troughs are fed with the shielding cover, the receiving plate returns to the designated position;

[0027] S3: The robot controls the clamping mechanism to simultaneously clamp the shielding covers in several material troughs;

[0029] S5: After gluing, the robot controls the clamping mechanism to move the clamped shielding cover to the top of the tray mechanism and align it with the unassembled inductor core on the material strip;

[0030] S6: The manipulator controls the clamping mechanism to move the clamped shielding cover downward in a full circle motion so as to put the shielding cover on the inductor core;

[0031] S7: The clamping mechanism releases the shielding cover and presses the shielding cover down once again to fully bond the shielding cover to the inductor core;

[0032] S8: After the assembly is completed, the robot returns to the position waiting for the material to be clamped and repeats the above steps;

[0033] S9: When one tray is completed on the assembly side, the tray rotating cylinder works to rotate the other side to be assembled to the assembly position, take out the assembled material from the tray material taking port, and replace the new tray.

[0034] Beneficial effects:

[0035] 1. The shielding cover is provided with a shielding cover slot. During the vibration feeding process, the shielding cover will be fed upward along the guide rail at various angles. The first screening air nozzle blows air to the shielding cover material on the guide rail. When the shielding cover slot is stuck in the first convex track, the airflow cannot blow the shielding cover, and the shielding covers at other angles will be blown off, thereby screening out the shielding cover materials with incorrect angles to ensure the accurate angle position of the material, and the convex track extends all the way to the material trough to ensure the consistency of the feeding material angle.

[0036] 2. A first infrared light sensor is provided on the linear feeding guide. The first infrared light sensor includes a first infrared light emitter and a first infrared light receiver, which are respectively located on both sides of the linear feeding guide. The first infrared light emitter emits infrared light that passes through the slot of the linear feeding guide to reach the first infrared light receiver. When a shielding cover is located in between, the infrared light will be blocked. When no shielding cover is located in between, the infrared light will be received by the first infrared light receiver. The control system will control the vibration feeding mechanism to start feeding. Here, the control system can set the feeding time. In the embodiment of the present invention, two groups of first infrared light sensors are provided. When the first infrared light sensor close to the material distribution device detects that there is no material, the system will continue to start the vibration feeding mechanism to feed until there is material blocking it, so as to ensure the continuity of feeding.

[0037] 3. The depth of the glue dispensing groove is 0.2 mm, which can accurately control the thickness of the glue on the shielding cover. The glue scraping mechanism scrapes the glue once after the shielding cover is glued once, ensuring that the glue thickness is uniform each time;

[0038] 4. The clamping mechanism uses spring buffering to protect the shielding cover. On the one hand, when gluing, the robot presses the clamping mechanism down to let the shielding cover clamped by the clamp touch the glue dispensing groove for gluing. The spring can act as a buffer to avoid the shielding cover from being broken or damaged by direct hard contact. On the other hand, when assembling, the shielding cover also needs to be pressed down to bond with the inductor core. During the pressing process, the spring can act as a buffer to avoid the shielding cover from being broken or damaged by direct hard contact.

[0039] 5. The device and method of the present invention can realize continuous automatic assembly, save labor and greatly improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, two are provided, and the first screening air nozzle 203 is connected to the air valve 103 pipeline. When the vibrating disk 201 is started, continuous blowing begins, and when the vibrating disk 201 stops, the blowing stops.

[0062] The air valve 103 is connected to a control system to control the opening and closing of the air valve. Of course, the air valve 103 is connected to an air compressor to supply compressed air or provide negative pressure adsorption.

[0063] like Fig.16 As shown, a shielding cover slot 903 is opened on the shielding cover 901. During the vibration feeding process, the shielding cover 901 will feed upward along the guide rail 202 at various angles. The first screening air nozzle 203 blows air towards the shielding cover 901 material on the guide rail 202. When the shielding cover slot 903 is stuck in the first protruding track 2021, the airflow cannot blow the shielding cover 901, and the shielding covers 901 at other angles will be blown off, thereby screening out the shielding cover 901 materials with incorrect angles to ensure the accurate angle position of the materials.

[0064] like Figure 2 , 3As shown, a linear feeding mechanism 3 is provided on the right side of the vibration feeding mechanism 2, and the linear feeding mechanism 3 includes a straight vibrator 301 and a linear feeding guide rail 302.

When a shielding cover 901 is located between them, the infrared light will be blocked. When no shielding cover 901 is located between them, the infrared light will be received by the first infrared light receiver 3042. The control system will control the vibration feeding mechanism 2 to start feeding. Here, the control system can set the feeding time. In this embodiment, two groups of first infrared light sensors 304 are set. When the first infrared light sensor 304 close to the material distribution device detects that there is no material, the system will continue to start the vibration feeding mechanism 2 to feed until there is material blocking it, so as to ensure the continuity of feeding.

One end of the guide rod 503 is fixed to the movable block 502, and the other end slides up and down on the fixed block 501. A spring 5031 is sleeved on the guide rod 503 between the fixed block 501 and the movable block 502. A plurality of clamping claws 504 are fixed on the movable block 502. The clamping claw 504 is provided with a fixed claw 5041 and a movable claw 5042. The movable claw 5042 is controlled pneumatically or electrically. The lower end of the fixed claw 5041 is provided with a slot for accommodating the shielding cover 901.

[0080] The inner edge of the lower end of the card slot is chamfered, which makes it easier to guide the shielding cover 901 into the card slot when grabbing the shielding cover 901.

[0081] Among them, the use of spring 5031 as a buffer can protect the shielding cover 901. Specifically, there are two points. On the one hand, when performing the gluing action, the robot 5 presses down the clamping mechanism to let the shielding cover 901 clamped by the clamp 504 touch the glue dispensing groove 6012 for gluing. The spring 5031 can act as a buffer to avoid direct hard contact with the lower shielding cover 901 to cause it to break or be damaged. On the other hand, when assembling, it is also necessary to press down the shielding cover 901 to bond with the inductor core 902. During the pressing process, the spring 5031 can act as a buffer to avoid direct hard contact with the lower shielding cover 901 to cause it to break or be damaged.

[0082] like Figure 1 As shown, a protective cover 101 is provided on the frame 1, and the protective cover 101 can protect the stable operation of the equipment and prevent safety accidents. A number of sealing doors are provided on the side of the protective cover 101. In this embodiment, sealing doors are provided on the front and rear sides. The sealing doors are convenient for adding materials, inspection and maintenance, and are equipped with opening and closing sensors. When the sealing doors are opened, the equipment stops or alarms. A pallet feeding port 102 is provided on the right side of the protective cover 101 to facilitate the replacement of pallets and facilitate loading and taking of materials.

[0083] The present invention provides an inductor shielding cover assembly method, using the above-mentioned assembly machine, specifically comprising the following steps:

[0084] S1: The vibration feeding mechanism 2 and the linear feeding mechanism 3 work to send the shielding cover 901 to the linear feeding guide rail 302;

[0085] S2: The linear feeding guide rail 302 cooperates with the material distribution mechanism 4 to sequentially feed the shielding cover 901 into the material placement slot 402. After all the material placement slots 402 are fed with the shielding cover 901, the receiving plate 401 returns to the designated position, and there is a clamping mechanism above the designated position;

[0086] S3: the robot 5 controls the clamping mechanism to simultaneously clamp the shielding covers 901 in the plurality of material troughs 402;

[0087] S4: The glue scraping mechanism 6 scrapes the glue, and the robot 5 controls the clamping mechanism to move the clamped shielding cover 901 to the top of the glue dispensing groove 6012, and the clamping mechanism presses down to make the shielding cover 901 contact the glue dispensing groove 6012 for gluing;

[0088] The scraping action of the scraping mechanism 6 only needs to be completed before gluing.

[0089] S5: After gluing, the robot 5 controls the clamping mechanism to move the clamped shielding cover 901 to the top of the tray mechanism 7 and align it with the unassembled inductor core 902 on the material strip 704;

[0090] S6: The manipulator 5 controls the clamping mechanism to move the clamped shielding cover 901 downward in a circular motion so as to fit the shielding cover 901 onto the inductor core 902.

[0091] Among them: For the SS70XX series inductor products, the gap between the shielding cover 901 (IR) and the inductor core 902 (DR) is small. If the assembly operation is carried out vertically downward, it is very difficult to complete the assembly. The IR is prone to tipping over, and the shielding cover 901 is easily damaged by being pressed. The circular motion assembly is to make the manipulator 5 control the clamping mechanism to make the clamped shielding cover 901 move in a circular motion with a small radius around the axis of the inductor core 902 when the lower end of the shielding cover 901 contacts the upper end of the inductor core 902, which is convenient for the shielding cover 901 to be sleeved onto the inductor core 902.

[0092] S7: The clamping mechanism releases the shielding cover 901 and then presses the shielding cover 901 downward once to make the shielding cover 901 fully adhered to the inductor core 902.

[0093] S8: After the assembly is completed, the manipulator 5 returns to the position waiting to clamp the material and repeats the above steps.

[0094] S9: When one tray is completed on the assembly side, the tray rotating cylinder works to rotate the other side waiting for assembly position to the assembly position, take out the assembled material from the tray material taking port 102, and replace with a new tray.
